摘　　要：条带剖面提取方法是利用数理统计原理,获得垂直于剖面线方向上一定缓冲区范围的高程信息,计算最大、最小和平均高程以及地形起伏度,把地形剖面图对线状地形起伏特征的描述转化为对面状地形起伏特征的描述。该文基于ArcGIS 9.3对三峡地区SRTM-DEM数据进行了条带剖面提取方法研究,实现了基于ArcGIS的条带剖面提取技术流程。应用条带剖面对三峡地区地形地貌进行了定量分析,该方法可快速提取条带剖面,能准确获取高程属性的相关统计参数,对地形地貌信息提取和定量分析具有一定价值。The swath profile extraction according to the principle of mathematical statistics has been applied to obtain the elevation information from a certain area of the buffer zone which is perpendicular direction of the terrain profile line.It is the calculated maximum elevation,minimum elevation,average elevation and relief amplitude.In this paper,the SRTM-DEM data of the Three Gorges region was analyzed by swath profile extraction based on ArcGIS 9.3.The basic procedures and processes of swath profile extraction were given.The landform of the Three Gorges region quantitatively has also been analyzed by curves of the swath profile.The result shows that the statistics of the elevated properties,such as maximum elevation,minimum elevation,average elevation and relief amplitude,can be accurately obtained by swath profile extraction.It suggests that this extraction procedure is an effective method to analyze the landform information quantitatively.
